Burning Carbs: Timing Your Keto Transition

The ketogenic diet is a low-carbohydrate method of eating that aims to put the body into a state of ketosis, where it uses fat as its primary fuel source. When beginning a keto diet, it is recommended to limit carbohydrates to less than 20 grams per day for the first two weeks to suppress carb cravings and accelerate keto adaptation. Consuming excess carbs can kick the body out of ketosis, as it will start using glycogen stores before turning to fat reserves. The time it takes to burn off carbs depends on various factors, including the amount and type of carbs consumed, physical activity levels, and individual differences. While there is limited scientific data on the exact time it takes to burn off carbs, some sources suggest that 1 gram of carbs can be burned off in a couple of minutes, especially with intense physical activity.

Excess carbs go to muscle glycogen stores, then fat is burned

Excess carbohydrates are stored in the body as glycogen, which is a readily available source of energy. Glycogen is stored in the liver and muscles, with small amounts also found in the brain, heart, kidney, and fat cells. The liver uses glycogen to maintain blood glucose levels, while muscle glycogen is used to power the muscles during physical activity.

When the body needs energy, it draws on these glycogen stores. The rate at which muscle glycogen is used depends on the intensity of physical activity. High-intensity exercises like sprinting or heavy lifting can quickly deplete glycogen stores, while lower-intensity exercises such as walking will use glycogen more slowly.

Once the body's glycogen stores are depleted, it will start to burn fat for energy. This is the principle behind the ketogenic diet, which aims to deplete glycogen stores and force the body to burn fat instead. However, it is important to note that the body is constantly burning a mixture of carbohydrates and fat, and the ratio of these depends on activity levels. At rest or during low-intensity activities, fat contributes around 80% of the body's energy, while carbohydrates make up the remaining 20%. As exercise intensity increases, the contribution of carbohydrates to energy production increases, and fat burning decreases.

Therefore, to burn off excess carbohydrates, one would need to engage in physical activity. The type and intensity of the activity will determine how quickly glycogen stores are depleted and fat burning begins. Additionally, dietary factors such as calorie intake and the amount of carbohydrates consumed will also impact how the body utilizes energy sources.

Working out harder may help minimise the impact of excess carbs

If you have ever felt sluggish or low on energy during a workout, you probably didn't fuel up with enough carbs. Choosing snacks that are high in carbs and easy to digest, such as bananas, English muffins with jam, or granola bars before exercise helps maintain optimal levels of blood glucose for our muscles.

Consuming carbohydrates after exercise helps replenish the energy used during strenuous exercise. This is especially true for activity longer than one hour, and requires extra attention to carb refuelling. Muscles need protein and carbohydrates to properly recover and become stronger.

A post-exercise recovery shake with a 3:1 ratio of carbohydrates to protein is the perfect way to refuel. For example, try blending Herbalife24® Rebuild Strength with a banana and 8 ounces of milk to optimise your recovery.

Whether you're an athlete, fitness enthusiast, or just trying to lose a few pounds, carbohydrates are an important part of an optimal diet for consistent performance and recovery. Instead of cutting carbs completely, choose the right carbs before and after your workouts.

The body will not easily switch to fat-burning mode without consistency

During the initial stages of a ketogenic diet, it is crucial to strictly limit your carb intake to facilitate the transition to fat-burning mode. Aim for less than 20 grams of carbohydrates per day during the first two weeks to curb carb cravings and accelerate keto adaptation. This initial period sets the tone for your body to become accustomed to utilizing fat for energy instead of relying on carbohydrates.

The body's preference for carbohydrates as a fuel source is strong, and it takes time and consistency to shift this preference towards fat burning. By being consistent with your carb restriction, you can effectively deplete your body's glycogen stores (glucose stored in muscles and liver). This depletion triggers a shift towards burning fat for energy, as the body seeks alternative fuel sources.

However, succumbing to carb cravings can hinder this process. If you consume significantly more carbs than your target amount, you may disrupt the adaptation process and delay entering ketosis. Consistency in your carb intake helps reinforce the body's reliance on fat for fuel, gradually reducing the urge for carbohydrates.

It's important to note that everyone's body is unique, and the transition to fat-burning mode may vary slightly from person to person. However, by maintaining consistency in your keto diet, you can ensure that your body adapts effectively and efficiently to utilizing fat as its primary energy source.

Low-carb diets deplete the body's glycogen supplies, leading to water weight loss

Low-carb diets, such as the ketogenic diet, are popular for weight loss due to their ability to induce rapid weight loss, especially at the beginning of the diet. This rapid weight loss is often attributed to the depletion of the body's glycogen stores and subsequent water loss.

Glycogen is the stored form of glucose, which is found in the muscles and liver. When carbohydrates are restricted, the body quickly uses up its glycogen reserves, leading to a significant loss of water weight. This is because for every gram of glycogen, there is an associated loss of three grams of water. As a result, individuals may experience an increase in urination and a rapid drop in weight within the first few days of starting a low-carb diet.

The amount of water weight lost can be substantial, as the typical glycogen weight in the muscles is around 500 grams, resulting in a potential water weight loss of up to 1,500 grams (3.3 pounds). This initial weight loss can be highly motivating for individuals starting a new diet regimen. However, it is important to note that this water weight will be regained if the diet is not adhered to and high-carbohydrate meals are consumed.

To maintain weight loss and prevent regaining water weight, it is crucial to consistently follow a low-carb diet and avoid high-carbohydrate meals. Additionally, creating a significant energy deficit by consuming fewer calories than the body uses will promote further weight loss. This can be achieved through a combination of reducing calorie intake and increasing physical activity.

While low-carb diets can be effective for weight loss, it is important to prioritize the overall healthiness of the diet. Low-carb diets may lack essential nutrients and increase the risk of constipation due to the exclusion of nutrient-rich vegetables, fruits, and high-fiber whole grains. Therefore, it is recommended to seek advice from a health professional, such as a dietitian or doctor, before starting a low-carb diet.

A low-carb diet is most effective for weight loss with insulin resistance or diabetes

A low-carb diet can be an effective way to manage weight and improve health for people with insulin resistance or diabetes. Carbohydrates raise blood glucose levels more than other foods, requiring the body to produce more insulin to digest them. This can be challenging for people with insulin resistance or diabetes, as their bodies may struggle to effectively utilise insulin.

A low-carb diet can help stabilise blood glucose levels and may also counteract some of the effects of diabetes, such as weight gain and heart disease. For people with insulin resistance, blood glucose may remain elevated for hours after consuming carbohydrates. A low-carb diet can reduce these spikes, promote weight loss, and encourage fat metabolism.

Research has shown that a low-carb diet can lead to significant weight loss and improved glycemic control in obese individuals with type 2 diabetes. Additionally, insulin sensitivity improved, while systolic blood pressure and cholesterol measurements showed positive changes, reducing the risk of cardiovascular disease.

However, it is important to note that low-carb diets also carry some risks and may not be sustainable in the long term. They can lead to vitamin and mineral deficiencies, and some people may find them challenging to adhere to over time. It is always recommended to consult a healthcare professional before making significant dietary changes, especially for those managing a health condition such as diabetes.

When considering a low-carb diet for weight loss with insulin resistance or diabetes, it is crucial to prioritise nutritional adequacy and sustainability. This may include ensuring adequate fibre intake, being mindful of saturated fat consumption, and limiting the use of artificial sweeteners. Additionally, it is important to remember that not all carbohydrates are equal; prioritising complex carbohydrates high in fibre, such as whole grains and starchy vegetables, can provide additional health benefits.

While a low-carb diet can be a valuable tool for managing weight and blood glucose levels in individuals with insulin resistance or diabetes, it should be approached with caution and under the guidance of a healthcare professional to ensure safety and effectiveness.
